She's been inspired by her best pal Sadie Frost, who wants to open herself up to meetingh a decent man too and has even given up alcohol for seven weeks to help her find a Mr Right.

The friend says: "Sadie sees her therapist three times a week and is going back to her childhood to discover why she goes in for too much drink, other substances and partying."

Kate was so impressed by her party partner that she's decided to join her in the quest for a better lifestyle and better men.

Close friends for years, the girls have always shared everything - drinks, secrets, boyfriends - and now they will even share a therapist.

A pal of the pair told us: "Sadie's been dry for the past seven weeks and has been seeing a female therapist. Having been influenced by Sadie's new take on life Kate is following in her footsteps and intends to see the same therapist to sort out the same issues.

"Kate's seen what a difference it has made to Sadie's life and how much happier she is, so she wants to go back to her past and try to come out much stronger."

Now, as part of her dramatic bid to reinvent herself, Sadie is sending her four children to live with Hollywood star Jude as she embarks on a three-month #250,000 makeover of her Primrose Hill home.

And in a complete change from her champagne-fuelled lifestyle, Sadie is doing a run for charity. Getting into shape for Sports Relief on July 15, she has been training four times a week.

To help Kate and Sadie make a fresh start, their friend, party organiser Fran Cutler, is whisking them off to a detox retreat in the Maldives. They will be pampered for five days at the swanky One&Only resort Reethi Rah.

The friend tells us: "Kate and Sadie have always done things together, and now they both feel they will never find Mr Right if they carry on their old lives."

Good luck, girls. Remember to swap those vodka shots for virgin pina coladas.
